I'm sure there are some exceptions but, generally, RT's make a lot less than RN's in California ... about $15K less a year on average, according to the Bureau of Labor Statistics.
I personally think it's because RT's aren't unionized like RN's are in this state. Just at one local hospital in my area, the union negotiated pay raises where new grad RN's now make more than veteran RT's.
The RT's had a chance to go union at that same facility a couple of years ago but, they voted against it ... believing management's promises that they would get a pay raise. Needless to say, management renigged. My guess is that this sort of thing has happened elsewhere since the pay difference is substantial.
I also like the fact that nursing has so many specialities. Now that I've finally graduated, I'm constantly amazed at the number of things I can do with this degree.
I know it's frustrating but ... I must say it was worth the wait and, with a $15K annual pay differential on average, will probably pay off in the end.
